For Oracle9i and higher, the Oracle driver supports the Oracle XMLType data type. Which JDBC data type the XMLType data type is mapped to depends on whether the JDBCBehavior property is set. If JDBCBehavior=0, the driver maps the XMLType data type to the JDBC SQLXML data type.
Note: For Oracle 12c R1, the driver supports XMLType columns with binary storage if SupportBinaryXML=true. For Oracle 12c R2 and higher, the driver supports XMLType columns with binary storage by default.. Starting with Oracle 11.2.0.2, the default XML storage type was changed from CLOB to BINARY.
